Feature Request - Adding an Eraser Tool to the Masking Interface

[igorhero76-dev]

Hello,

First of all, thank you for the amazing work on Fooocus Plus. The workflow is already quite smooth, but I'd like to suggest a feature that would significantly improve the precision of the Inpaint/Outpaint process: an Eraser tool for mask creation.

Currently, when using automatic mask generation models (like isnet-general-use), the selection can sometimes be too broad, especially when subjects are close to each other.

To illustrate the need, here is a practical scenario:

**Image A** (Initial Auto-Mask): In this example, the model automatically masks both subjects because they are close and similar. However, I might only want to modify one of them. **Image B** (The "Eraser" Goal): With an eraser tool, I could easily "rub out" the unwanted part of the white mask to isolate only the subject I want to inpaint. This is much faster than trying to manually paint a perfect mask from scratch. **Image C** (Final Result): Thanks to that refined mask, the inpainting is surgical. I can replace one subject (here, the man on the left replaced by a woman) without the AI interfering with the rest of the scene.

-Adding a simple toggle between a Brush (to add to the mask) and an Eraser (to remove parts of it) would give users professional-level control directly within the Fooocus Plus interface.

What do you think about adding this to the roadmap?

Best regards,

@igorhero76-dev This would be an excellent feature! Fooocus Inpainting has always outstanding but the inability to erase has always been frustrating. I have a feeling that the Gradio 3.43.2 user interface (UI) that we currently use cannot do it, and even though there were many requests in the original Fooocus Github discussion section it never happened.

I have been upgrading to Gradio 5.5. It has a new painting interface and I have a feeling that erasure will be supported there. The process has been taking months because most of the UI has to be rewritten. It will be some months more before that process will be complete. But likely we will finally have Inpainting erasure on the Fooocus based platform after that.

I am transferring this discussion to the Feature Request section so that it does not get lost. See #341
